摘要
本文研究了双相不锈钢材料 S32101采用手工电弧焊焊接接头的金相组织、力学性能和抗晶间腐蚀性能。结果表明，采用多层多道焊接，焊接电压为22～25V ，焊接电流为100～110A ，线能量27～30 kJ/cm ，控制层间温度在150℃左右可使焊接接头获得合理相比例的奥氏体和铁素体组织，保证焊接接头具有良好的力学性能和抗晶间腐蚀能力。
This paper studies the duplex stainless steel material S32101 using manual arc welding welding joint microstructure , mechanical properties and intergranular corrosion resistance . Results show that when we use multilayer multi-pass welding , we should control the welding voltage to be 22~25V , the welding current to be 100~110A , the energy input to be 27~30 kJ/cm , interpass temperature to be about 150 ℃, which can get reasonable proportion of austenite and ferrite and guarantee the welding joint having good mechanical properties and intergranular corrosion resistance .
